The technical scheme of the utility model: including first hinge, second hinge and the round pin axle of connecting first hinge, second hinge, first hinge is including last pin bushing and lower pin bushing, go up pin bushing, lower pin bushing and rotate with upper portion, the lower part of round pin axle respectively and be connected, the material of round pin axle is elastic plastic, the lower part of round pin axle is provided with barb portion, barb portion is "U" style of calligraphy, and it is including butt section, changeover portion and the link of connecting butt section and changeover portion, changeover portion and round pin axle body coupling, form the inside groove that supplies the inside atress compression of butt section between butt section, changeover portion and the link, the butt section is supported the cooperation and can be interlude under compression in lower pin bushing with lower pin bushing under the state of relaxing.

Adopt above-mentioned technical scheme, barb portion has certain elasticity, can penetrate first hinge and second hinge when the pressurized, run through the hinge after can replying the shape and lean on the lower extreme that leans on at the cotter way down, and on the same reason, it also can pull down the round pin axle to press barb portion, so, just can adorn or pull down the round pin axle through pressing barb portion, whole dismouting process need not the instrument and participates in, the operating personnel dismouting is more convenient, the operation degree of difficulty is little, time saving and labor saving, structural design is reasonable effective.

The utility model discloses a further setting: the upper part of the pin shaft is convexly provided with a boss, and the boss is abutted with the lower pin sleeve to form limiting fit.

Adopt above-mentioned further setting, structural design is simple and can form spacing effect with lower round pin cover, still promotes spacing effect when having reduced the processing degree of difficulty.

The utility model discloses a further setting again: the upper part of the pin shaft extends integrally with a drag hook rod for holding and pulling by people.

Adopt above-mentioned further setting again, grip the pull hook rod and can wear the bolt axle or lift the round pin axle off to round pin axle axial direction application of force, further reduce the participation degree of instrument, the dismouting is convenient and fast more.

The utility model discloses a still further set up: the pin shaft is made of polyformaldehyde resin.

By adopting the further arrangement, the characteristics of high strength and rigidity, good elasticity, good abrasion resistance and wear resistance and the like of the polyformaldehyde resin are utilized, so that the novel hinge pin can be well applied to the hinge pin, and the material is properly selected.

The utility model discloses a still further set up: the link is the frustum shape, the link is from the lower extreme diameter crescent upwards.

Adopt above-mentioned still further setting again, be equivalent to carry out the chamfer to the link, during the round pin axle of being convenient for inserted the hinge, convenient degree further promotes.

Detailed Description

As shown in fig. 1 and 2, the hinge convenient to disassemble and assemble comprises a first hinge 2, a second hinge 3 and a pin shaft 1 connected with the first hinge 2 and the second hinge 3, wherein the first hinge 2 comprises an upper pin sleeve 21 and a lower pin sleeve 22, the upper pin sleeve 21 and the lower pin sleeve 22 are respectively rotatably connected with the upper part and the lower part of the pin shaft 1, the pin shaft 1 is made of elastic plastic, the lower part of the pin shaft 1 is provided with a barb part 11, the barb part 11 is in a U shape and comprises a butt joint section 111, a transition section 112 and a connecting end 113 connected with the butt joint section 111 and the transition section 112, and the transition section 112 is integrally connected with the pin shaft 1, namely the barb part 11 and the pin shaft 1 are integrally formed; an internal groove 114 is formed between the abutment section 111, the transition section 112 and the connecting end 113 for inward forced compression of the abutment section 111. The barb part 11 has certain elasticity, presses the butt section 111 inwards, can reduce the groove width of interior groove 114, reduces the distance between butt section 111 and the changeover portion 112, makes the overall dimension of whole barb part 11 be less than the diameter of upper pin bush 21 or lower pin bush 22 to when butt section 111 is pressed, round pin axle 1 can penetrate upper pin bush 21 and lower pin bush 22. Wait to run through whole hinge promptly pressure disappearance back, butt section 111 restores the shape because of elastic force, and at this moment, the distance between butt section 111 and the changeover portion 112 restores and enlarges, and is greater than the diameter of lower cotter 22, and butt section 111 supports and makes round pin axle 1 receive spacingly by the lower extreme of cotter 22 under so, and whole hinge forms articulated effect. Similarly, the pin shaft 1 can be removed by pressing the barb 11 to insert the barb 11 into the upper pin sleeve 21 and the lower pin sleeve 22.

The upper part of the pin shaft 1 is convexly provided with a boss 12, the boss 12 is propped against the lower pin sleeve 22 to form limit fit, namely the size of the boss 12 is larger than the diameter of the lower pin sleeve 22, and the contact surfaces between the boss 12 and the lower pin sleeve 22 are mutually propped against.

The upper part of the pin shaft 1 is integrally provided with a hook-shaped pull rod 13 in an extending way, and the hook-shaped pull rod 13 is used for being held by a person to pull out the pin shaft 1 or insert the pin shaft 1.

The material of the pin shaft 1 is polyformaldehyde resin, namely POM plastic, the mechanical property is excellent, the high-strength rigidity, the elasticity is good, the antifriction and wear resistance is good, and the high-strength rigidity can provide good rigidity and hardness for the pin shaft 1, ensure the structural stability of the hinge, ensure that the first hinge 2 and the second hinge 3 can keep long-term rotating fit due to wear resistance, and provide performance support for the barb part 11 due to good elasticity.

The connecting end 113 is frustum-shaped, the diameter of the connecting end 113 gradually increases from the lower end to the upper end, and the pin shaft 1 can be conveniently inserted into the hinge.
